l:uvrpaoven/:ENT IN sBoURING, Hires To xL-es.

The Schedule referred to' in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, GEORGE E. GLOW, of Jeffersonville, in the county of Clark and'State of Indiana, haveinvented a .new and improved Device for Securing Hubs to Axles; and Ido hereby declare that the following isa full, clear, and'exactdescription of the same, reference being had to the accompanying drawing forming a part of this specification, in which- Figure l is a cross-section, and

Figure 2 a longitudinal section.'

Hitherto the meansordex-ices for securing hubs to axle-journals, and the .oil-tubes connected therewith, have been separately applied. Hence, -t'wo or more radial perforations were required in the hub, with corresponding fittings, involving labor and eXpense,-and Wea-kening the hub, in additionto being otherwise objectionable. l

My invention has for its main, object the removal of these objections, and consists in the combination, with the hub and axle-journal box, of a channeled 0r groovedoiltube and a fastening key,'so arranged that thesaid box is secured in the hub by the tube, whichv be4 not filled by the' key, Yinto which'oil may be poured. The recesses do not 'extend to the bottom ofthe tube, and .the orilce infwhich.` the key isplaced is entirely closed by the latter. at its inner end, so as to prevent the escape of ythe oil, except when 'the key is ren1oved, which may be'done, and the axle thus lubricated without remov# ing the wheel. 4 v The cap 'l is furnished with a rubber packing, which tightly closes thetube when the cap is screwed down.

l .The tube also serves to secure the axle-box in the hub. No packing isrequired to keep the wheel in its properpostion. A

1t' will be observed that the key requires to belonly partly withdrawn fromthc tube iu order to admit the oil, a-srnall quantity-of which may berretained in the chamber la for use on another or vthe next occasion.

` By' this arrangement I providea simple, cheap, sec'ure, andconve'nient fastening for the ]onrnal-box, as well as theaxle, and avoid perforating the hub more than once. Axle-journals and hubs Aof the ordinary kind may be easily converted to be secured together by the mea-ns described.

Having thus described my invention,

What I claim as new, and desire to secure by vLetl. The tube b, provided with the channels or grooves 7c, and screwed through the hub A and into the journal-box a, as and for the purpose shown and described. 2. The axle-journal e, box c, and hub A, secured together by the screw-threaded oil-tube b and -vkey c, all'constructed and arranged as shown and described, for the purpose' specified. l

GEO. E. GLOW.
